We believe, that at Creation, YHVH, established a calendar. In Genesis we see that He established, Day, Night and the week. Later in Torah He established the natural months and instructed His people to observe it.
"Observe the month of Abib (the first month of the year in the Spring) and keep the Passover to the LORD your Elohim (God), for in the month of Abib the LORD your God brought you out of Egypt by night." Deuteronomy 16:1
We practice and encourage others to observe God's set-apart holy days, feasts and festivals.
"And the LORD spoke to Moses, saying, "Speak to the children of Israel, and say to them: 'The feasts of the LORD, which you shall proclaim to be holy convocations, these are My feasts." Leviticus 23:1-2
The Apostles and first century saints also observed these appointed times:
"But concerning the times and the seasons, brethren, you have no need that I should write to you. For you yourselves know perfectly that the day of the LORD so comes as a thief in the night." I Thessalonians 5:1-2
The Apostles did not need to instruct the believers in these things because they were already observing these days.
To determine these days, we observe the Biblical Calendar, as laid out in Leviticus 23, and throughout Torah. To learn more about the Biblical Calendar that we observe, please check-out our teachings on this subject:

*Please note that these dates are based on calculations, but the actual date for observance is based on the sightings of the new moon. We follow that as we desire to be unified with the saints in Israel, as one bride, we look for the observation in the New Moon as it is sighted in Israel.
